Hello Pete, a recent tv prog showed the Prescelly outcrop. Several large pieces of blue stone were separated/split and wedged apart with smaller stones. It was implied that this was the work of the Stonehenge builders or at least, the quarrymen employed for the project. I was hoping for similar evidence to support the Marlbrough Downs theory. So, there is no evideence of a quarry in the area?
